Sysquake for LaTeX

Sysquake for LaTeX is a LaTeX package which offers the seamless integration of the Sysquake interpreter in LaTeX. Sysquake code fragments stored in the .tex files are evaluated and the result (text and graphics)
is included in the typeset output (PDF or DVI file) with ultimate quality and convenience.

Sysquake for LaTeX has been tested with MiKTeX on Windows and with TeXLive 2016 on macOS and Linux. Its installation does not depend on any TeX distribution; its operating, described in its documentation, should allow its use with other versions.

On Windows, Sysquake for LaTeX is provided in an installation program (.exe file). You should install LaTeX, typically the last release of MiKTeX or TeXLive, before Sysquake for LaTeX. The documentation provides more details.

On Mac, Sysquake for LaTeX is provided in an installation package (.pkg file), itself compressed with zip for an easier download. You should install LaTeX first, typically the last release of TeXLive. Then double-click the zip file, then the pkg file, and follow the instructions.

On Linux, Sysquake is provided either as a deb package for compatible distributions (including Ubuntu, Debian and Linux Mint), or in a tgz archive file for other distributions or a manual installation. You should install LaTeX first, typically the last release of TeXLive. Then install the deb package (e.g. by typing sudo dpkg -ifile.deb in a terminal) or unarchive the tgz file and read the readme file. The documentation provides more details.
